Ex- periment 4 tends to fhew that there exifled no fulphuric acid ; the exiflence of the muriatic acid is fuppofed from experiment 5 ; experi- ments 6, 7 and 8, prove the exiflence of acids; experiment 7,detects agum-refin; experiments 8 and 9, the lithic and phofphoric acids; ex- periment 14, detects pofitively the volatile alkali.
